30 Sulfur is not subject to the requirements of this subchapter if transported in a non- bulk packaging or if formed to a specific shape (for example, prills, granules, pel-lets, pastilles, or flakes). A bulk packaging containing sulfur is not subject to the placarding requirements of subpart F of this part, if it is marked with the appro-priate identification number as required by subpart D of this part. Molten sulfur must be marked as required by § 172.325 of this subchapter.

31 Materials which have undergone suffi-cient heat treatment to render them non- hazardous are not subject to the require-ments of this subchapter.

32 Polymeric beads and molding compounds may be made from polystyrene,


330

49 CFR Ch. I (10–1–05 Edition) § 172.102

poly(methyl methacrylate) or other poly-meric material.

33 Ammonium nitrites and mixtures of an inorganic nitrite with an ammonium salt are prohibited.

34 The commercial grade of calcium nitrate fertilizer, when consisting mainly of a dou-ble salt (calcium nitrate and ammonium nitrate) containing not more than 10 per-cent ammonium nitrate and at least 12 per-cent water of crystallization, is not subject to the requirements of this subchapter.

35 Antimony sulphides and oxides which do not contain more than 0.5 percent of ar-senic calculated on the total mass do not meet the definition of Division 6.1.

36 The maximum net quantity per package is 5 L (1 gallon) or 5 kg (11 pounds).

37 Unless it can be demonstrated by testing that the sensitivity of the substance in its frozen state is no greater than in its liquid state, the substance must remain liquid during normal transport conditions. It must not freeze at temperatures above ¥15 °C (5 °F).

38 If this material shows a violent effect in laboratory tests involving heating under confinement, the labeling requirements of Special Provision 53 apply, and the mate-rial must be packaged in accordance with packing method OP6 in § 173.225 of this sub-chapter. If the SADT of the technically pure substance is higher than 75 °C, the technically pure substance and formula-tions derived from it are not self-reactive materials and, if not meeting any other hazard class, are not subject to the re-quirements of this subchapter.

39 This substance may be carried under pro-visions other than those of Class 1 only if it is so packed that the percentage of water will not fall below that stated at any time during transport. When phlegmatized with water and inorganic inert material, the content of urea nitrate must not ex-ceed 75 percent by mass and the mixture should not be capable of being detonated by test 1(a)(i) or test 1(a)(ii) in the UN Manual of Tests and Criteria (IBR, see § 171.7 of this subchapter).

40 Polyester resin kits consist of two com-ponents: a base material (Class 3, Packing Group II or III) and an activator (organic peroxide), each separately packed in an inner packaging. The organic peroxide must be type D, E, or F, not requiring tem-perature control, and be limited to a quan-tity of 125 mL (4.22 ounces) per inner pack-aging if liquid, and 500 g (1 pound) if solid. The components may be placed in the same outer packaging provided they will not interact dangerously in the event of leak-age. Packing group will be II or III, accord-ing to the criteria for Class 3, applied to the base material.

43 The membrane filters, including paper separators and coating or backing mate-

rials, that are present in transport, must not be able to propagate a detonation as tested by one of the tests described in the UN Manual of Tests and Criteria, Part I, Test series 1(a) (IBR, see § 171.7 of this sub-chapter). On the basis of the results of suitable burning rate tests, and taking into account the standard tests in the UN Manual of Tests and Criteria, Part III, sub-section 33.2.1 (IBR, see § 171.7 of this sub-chapter), nitrocellulose membrane filters in the form in which they are to be trans-ported that do not meet the criteria for a Division 4.1 material are not subject to the requirements of this subchapter. Pack-agings must be so constructed that explo-sion is not possible by reason of increased internal pressure. Nitrocellulose mem-brane filters covered by this entry, each with a mass not exceeding 0.5 g, are not subject to the requirements of this sub-chapter when contained individually in an article or a sealed packet.

44 The formulation must be prepared so that it remains homogenous and does not separate during transport. Formulations with low nitrocellulose contents and nei-ther showing dangerous properties when tested for their ability to detonate, deflagrate or explode when heated under defined confinement by the appropriate test methods and criteria in the UN Man-ual of Tests and Criteria (IBR, see § 171.7 of this subchapter), nor classed as a Division 4.1 (flammable solid) when tested in ac-cordance with the procedures specified in § 173.124 of this subchapter (chips, if nec-essary, crushed and sieved to a particle size of less than 1.25 mm), are not subject to the requirements of this subchapter.

45 Temperature should be maintained be-tween 18 °C (64.4 °F) and 40 °C (104 °F). Tanks containing solidified methacrylic acid must not be reheated during trans-port.

46 This material must be packed in accord-ance with packing method OP6 (see § 173.225 of this subchapter). During transport, it must be protected from direct sunshine and stored (or kept) in a cool and well-ven-tilated place, away from all sources of heat.

47 Mixtures of solids that are not subject to this subchapter and flammable liquids may be transported under this entry without first applying the classification criteria of Division 4.1, provided there is no free liquid visible at the time the material is loaded or at the time the packaging or transport unit is closed. Except when the liquids are fully absorbed in solid material contained in sealed bags, each packaging must cor-respond to a design type that has passed a leakproofness test at the Packing Group II level. Small inner packagings consisting of sealed packets containing less than 10 mL of a Class 3 liquid in Packing Group II or


331


III absorbed into a solid material are not subject to this subchapter provided there is no free liquid in the packet.

48 Mixtures of solids which are not subject to this subchapter and toxic liquids may be transported under this entry without first applying the classification criteria of Divi-sion 6.1, provided there is no free liquid visible at the time the material is loaded or at the time the packaging or transport unit is closed. Each packaging must cor-respond to a design type that has passed a leakproofness test at the Packing Group II level. This entry may not be used for solids containing a Packing Group I liquid.

49 Mixtures of solids which are not subject to this subchapter and corrosive liquids may be transported under this entry with-out first applying the classification cri-teria of Class 8, provided there is no free liquid visible at the time the material is loaded or at the time the packaging or transport unit is closed. Each packaging must correspond to a design type that has passed a leakproofness test at the Packing Group II level.

50 Cases, cartridge, empty with primer which are made of metallic or plastic cas-ings and meeting the classification criteria of Division 1.4 are not regulated for domes-tic transportation.

51 This description applies to items pre-viously described as ‘‘Toy propellant de-vices, Class C’’ and includes reloadable kits. Model rocket motors containing 30 grams or less propellant are classed as Di-vision 1.4S and items containing more than 30 grams of propellant but not more than 62.5 grams of propellant are classed as Di-vision 1.4C.

52 This entry may only be used for sub-stances that do not exhibit explosive prop-erties of Class 1 (explosive) when tested in accordance with Test Series 1 and 2 of Class 1 (explosive) in the UN Manual of Tests and Criteria, Part I (incorporated by reference; see § 171.7 of this subchapter).

53 Packages of these materials must bear the subsidiary risk label, ‘‘EXPLOSIVE’’, and the subsidiary hazard class/division must be entered in parentheses imme-diately following the primary hazard class in the shipping description, unless other-wise provided in this subchapter or through an approval issued by the Asso-ciate Administrator, or the competent au-thority of the country of origin. A copy of the approval shall accompany the shipping papers.

54 Maneb or maneb preparations not meet-ing the definition of Division 4.3 or any other hazard class are not subject to the requirements of this subchapter when transported by motor vehicle, rail car, or aircraft.

55 This device must be approved in accord-ance with § 173.56 of this subchapter by the Associate Administrator.

56 A means to interrupt and prevent deto-nation of the detonator from initiating the detonating cord must be installed between each electric detonator and the detonating cord ends of the jet perforating guns before the charged jet perforating guns are of-fered for transportation.

57 Maneb or Maneb preparations stabilized against self-heating need not be classified in Division 4.2 when it can be dem-onstrated by testing that a volume of 1 m3 of substance does not self-ignite and that the temperature at the center of the sam-ple does not exceed 200 °C, when the sample is maintained at a temperature of not less than 75 °C ± 2 °C for a period of 24 hours, in accordance with procedures set forth for testing self-heating materials in the UN Manual of Tests and Criteria (IBR, see § 171.7 of this subchapter).

58 Aqueous solutions of Division 5.1 inor-ganic solid nitrate substances are consid-ered as not meeting the criteria of Division 5.1 if the concentration of the substances in solution at the minimum temperature encountered in transport is not greater than 80% of the saturation limit.

59 Ferrocerium, stabilized against corro-sion, with a minimum iron content of 10 percent is not subject to the requirements of this subchapter.

60 After September 30, 1997, an oxygen gen-erator, chemical, that is shipped with its means of initiation attached must incor-porate at least two positive means of pre-venting unintentional actuation of the generator, and be classed and approved by the Associate Administrator. The proce-dures for approval of a chemical oxygen generator that contains an explosive means of initiation (e.g., a primer or elec-tric match) are specified in § 173.56 of this subchapter. Each person who offers a chemical oxygen generator for transpor-tation after September 30, 1997, shall: (1) ensure that it is offered in conformance with the conditions of the approval; (2) maintain a copy of the approval at each fa-cility where the chemical oxygen gener-ator is packaged; and (3) mark the ap-proval number on the outside of the pack-age.

61 A chemical oxygen generator is spent if its means of ignition and all or a part of its chemical contents have been expended.

64 The group of alkali metals includes lith-ium, sodium, potassium, rubidium, and caesium.

65 The group of alkaline earth metals in-cludes magnesium, calcium, strontium, and barium.

49 CFR Ch. I (10–1–05 Edition) § 172.102

66 Formulations of these substances con-taining not less than 30 percent non-vola-tile, non-flammable phlegmatizer are not subject to this subchapter.

70 Black powder that has been classed in ac-cordance with the requirements of § 173.56 of this subchapter may be reclassed and of-fered for domestic transportation as a Di-vision 4.1 material if it is offered for trans-portation and transported in accordance with the limitations and packaging re-quirements of § 173.170 of this subchapter.

74 During transport, this material must be protected from direct sunshine and stored or kept in a cool and well-ventilated place, away from all sources of heat.

77 For domestic transportation, a Division 5.1 subsidiary risk label is required only if a carbon dioxide and oxygen mixture con-tains more than 23.5% oxygen.

78 This entry may not be used to describe compressed air which contains more than 23.5 percent oxygen. An oxidizer label is not required for any oxygen concentration of 23.5 percent or less.

79 This entry may not be used for mixtures that meet the definition for oxidizing gas.

81 Polychlorinated biphenyl items, as de-fined in 40 CFR 761.3, for which specifica-tion packagings are impractical, may be packaged in non-specification packagings meeting the general packaging require-ments of subparts A and B of part 173 of this subchapter. Alternatively, the item itself may be used as a packaging if it meets the general packaging requirements of subparts A and B of part 173 of this sub-chapter.

101 The name of the particular substance or article must be specified.

102 The ends of the detonating cord must be tied fast so that the explosive cannot es-cape.The articles may be transported as in Division 1.4 Compatibility Group D (1.4D) if all of the conditions specified in § 173.63(a) of this subchapter are met.

103 Detonators which will not mass deto-nate and undergo only limited propagation in the shipping package may be assigned to 1.4B classification code. Mass detonate means that more than 90 percent of the de-vices tested in a package explode prac-tically simultaneously. Limited propaga-tion means that if one detonator near the center of a shipping package is exploded, the aggregate weight of explosives, exclud-ing ignition and delay charges, in this and all additional detonators in the outside packaging that explode may not exceed 25 grams.

105 The word ‘‘Agents’’ may be used instead of ‘‘Explosives’’ when approved by the As-sociate Administrator.

106 The recognized name of the particular explosive may be specified in addition to the type.

107 The classification of the substance is ex-pected to vary especially with the particle size and packaging but the border lines have not been experimentally determined; appropriate classifications should be verified following the test procedures in §§ 173.57 and 173.58 of this subchapter.

108 Fireworks must be so constructed and packaged that loose pyrotechnic composi-tion will not be present in packages during transportation.

109 Rocket motors must be nonpropulsive in transportation unless approved in ac-cordance with § 173.56 of this subchapter. A rocket motor to be considered ‘‘nonpropul-sive’’ must be capable of unrestrained burning and must not appreciably move in any direction when ignited by any means.

110 Fire extinguishers transported under UN1044 may include installed actuating cartridges (cartridges, power device of Di-vision 1.4C or 1.4S), without changing the classification of Division 2.2, provided the aggregate quantity of deflagrating (propel-lant) explosives does not exceed 3.2 grams per extinguishing unit.

111 Explosive substances of Division 1.1 Compatibility Group A (1.1A) are forbidden for transportation if dry or not desen-sitized, unless incorporated in a device.

113 The sample must be given a tentative approval by an agency or laboratory in ac-cordance with § 173.56 of this subchapter.

114 Jet perforating guns, charged, oil well, without detonator may be reclassed to Di-vision 1.4 Compatibility Group D (1.4D) if the following conditions are met:

a. The total weight of the explosive contents of the shaped charges assembled in the guns does not exceed 90.5 kg (200 pounds) per vehicle; and

b. The guns are packaged in accordance with Packing Method US 1 as specified in § 173.62 of this subchapter.

115 Boosters with detonator, detonator as-semblies and boosters with detonators in which the total explosive charge per unit does not exceed 25 g, and which will not mass detonate and undergo only limited propagation in the shipping package may be assigned to 1.4B classification code. Mass detonate means more than 90 percent of the devices tested in a package explode practically simultaneously. Limited propa-gation means that if one booster near the center of the package is exploded, the ag-gregate weight of explosives, excluding ig-nition and delay charges, in this and all additional boosters in the outside pack-aging that explode may not exceed 25 g.

116 Fuzes, detonating may be classed in Di-vision 1.4 if the fuzes do not contain more than 25 g of explosive per fuze and are made and packaged so that they will not cause functioning of other fuzes, explosives or other explosive devices if one of the


333


fuzes detonates in a shipping packaging or in adjacent packages.

117 If shipment of the explosive substance is to take place at a time that freezing weather is anticipated, the water con-tained in the explosive substance must be mixed with denatured alcohol so that freezing will not occur.

118 This substance may not be transported under the provisions of Division 4.1 unless specifically authorized by the Associate Administrator.

119 This substance, when in quantities of not more than 11.5 kg (25.3 pounds), with not less than 10 percent water, by mass, also may be classed as Division 4.1, pro-vided a negative test result is obtained when tested in accordance with test series 6(c) of the UN Manual of Tests and Criteria (IBR, see § 171.7 of this subchapter).

120 The phlegmatized substance must be significantly less sensitive than dry PETN.

121 This substance, when containing less al-cohol, water or phlegmatizer than speci-fied, may not be transported unless ap-proved by the Associate Administrator.

123 Any explosives, blasting, type C con-taining chlorates must be segregated from explosives containing ammonium nitrate or other ammonium salts.

125 Lactose or glucose or similar materials may be used as a phlegmatizer provided that the substance contains not less than 90%, by mass, of phlegmatizer. These mix-tures may be classified in Division 4.1 when tested in accordance with test series 6(c) of the UN Manual of Tests and Criteria (IBR, see § 171.7 of this subchapter) and approved by the Associate Administrator. Testing must be conducted on at least three pack-ages as prepared for transport. Mixtures containing at least 98%, by mass, of phlegmatizer are not subject to the re-quirements of this subchapter. Packages containing mixtures with not less than 90% by mass, of phlegmatizer need not bear a POISON subsidiary risk label.

49 CFR Ch. I (10–1–05 Edition) § 172.102

TP3 The maximum degree of filling (in %) for solids transported above their melting points and for elevated temperature liquids shall be determined by the following:

Degree of filling = 95d

dr

f

.

Where: df and dr are the mean densities of the liquid at the mean temperature of the liquid during filling and the maximum mean bulk temperature during transport respectively.

TP4 The maximum degree of filling for portable tanks must not exceed 90%.

TP5 For a portable tank used for the transport of flammable refrigerated liquefied gases or refrigerated liquefied oxygen, the maximum rate at which the portable tank may be filled must not exceed the liquid flow capacity of the primary pressure relief sys-tem rated at a pressure not exceeding 120 percent of the portable tank’s design pres-sure. For portable tanks used for the trans-port of refrigerated liquefied helium and re-frigerated liquefied atmospheric gas (except oxygen), the maximum rate at which the tank is filled must not exceed the liquid flow capacity of the pressure relief device rated at 130 percent of the portable tank’s design pressure. Except for a portable tank con-taining refrigerated liquefied helium, a port-able tank shall have an outage of at least two percent below the inlet of the pressure relief device or pressure control valve, under conditions of incipient opening, with the portable tank in a level attitude. No outage is required for helium.

TP6 The tank must be equipped with a pressure release device which prevent a tank from bursting under fire engulfment condi-tions (the conditions prescribed in CGA pam-phlet S–1.2 (see § 171.7 of this subchapter) or alternative conditions approved by the Asso-ciate Administrator may be used to consider the fire engulfment condition), taking into account the properties of the hazardous ma-terial to be transported.

TP7 The vapor space must be purged of air by nitrogen or other means.

TP8 A portable tank having a minimum test pressure of 1.5 bar (150 kPa) may be used when the flash point of the hazardous mate-rial transported is greater than 0 °C (32 °F).

TP9 A hazardous material assigned to special provision TP9 in Column (7) of the § 172.101 Table may only be transported in a portable tank if approved by the Associate Administrator.

TP10 The portable tank must be fitted with a lead lining at least 5 mm (0.2 inches) thick. The lead lining must be tested annu-ally to ensure that it is intact and func-tional. Another suitable lining material may be used if approved by the Associate Admin-istrator.

TP12 This material is considered highly corrosive to steel.

TP13 Self-contained breathing apparatus must be provided when this hazardous mate-rial is transported by sea.
